Abstract
The device includes two opposing lateral wings forming the right and left sides of the scraping device. Each wing includes an upper section through which the wing is attached to the central support about a vertical pivot axis, and a bottom section that is pivotable with respect to the upper section about a first horizontal pivot axis. Each wing can follow the unevenness of the roadway surface and may also include parts that can pivot backwards in case of a frontal impact with an obstacle. The scraping device offers a very high degree of versatility and can clean various kinds of roadway surfaces with an unprecedented level of efficiency.

A scraping device for cleaning a roadway surface, the scraping device having a right side, a left side and a lowermost edge, and forming a continuous overall front surface, the scraping device including:
- a central support and two opposing lateral wings forming the right and left sides of the scraping device, each wing extending along a horizontal axis in a lateral direction between an inner edge and an outer edge, and having a front surface, the inner edge of each wing being configured to pivot about a vertical pivot axis, each wing including:
- an upper section through which the wing is attached to the vertical pivot axis, the upper section having a lowermost edge;
- a bottom section pivotable relative to the upper section about a horizontal pivot point, the horizontal pivot point being located at a position that is adjacent to the vertical pivot axis and also adjacent to the lowermost edge of the upper section, the upper and bottom sections of each wing being in a sliding engagement with one another;
- an actuator mounted between the central support and the upper section of the wing to pivot the wing about the vertical pivot axis;
- and
- a first force-generating mechanism mounted between the upper section and the bottom section to exert a first return force along a transversal axis that intersects the horizontal axis urging the bottom section downwards with reference to the upper section, wherein the first force-generating mechanism extends along the transversal axis that intersects the horizontal axis.

- a bottom section pivotable relative to the upper section about a horizontal pivot point, the horizontal pivot point being located at a position that is adjacent to the vertical pivot axis and also adjacent to the lowermost edge of the upper section, the bottom section of each wing including:
- a first subsection through which the bottom section is pivotally attached to the upper section, the first subsection remaining parallel to a corresponding portion of the upper section when the bottom section is pivoted about the horizontal pivot point, the first subsection having a lowermost edge;
- and
- a second subsection positioned below the first subsection;
- an actuator mounted between the central support and the upper section of the wing to pivot the wing about the vertical pivot axis;
- and
- a first force-generating mechanism mounted between the upper section and the bottom section to exert a first return force along a transversal axis that intersects the horizontal axis urging the bottom section downwards with reference to the upper section, wherein the first force-generating mechanism extends along the transversal axis that intersects the horizontal axis.
